A 3-year-old girl whose death Friday was ruled a homicide had been in the care of her father at the family's Hurst apartment, but no one has been arrested, Hurst police said Sunday.
The child's mother was not in the apartment when the child died, police said.
"We're still in the interviewing process," Hurst Assistant Police Chief Richard Winstanley said Sunday. "There are indications of prior bruising before she was found Friday."
Officials with Child Protective Services also are investigating.

"There is no record of previous contact with the family," CPS spokeswoman Marissa Gonzales said Sunday. "There are no other children in the home."
Winstanley said that detectives are interviewing friends, family members and doctors involved in the case.
"We're also checking in with prosecutors in the Tarrant County district attorney's office," Winstanley said.
Winstanley said that he wasn't aware of any previous calls in which Hurst officers responded to the couple's home, where 3-year-old Anastasia Williams lived.
She was pronounced dead at 3:23 p.m. Friday from a laceration of the liver due to blunt trauma to the abdomen caused by an assault, according to the Tarrant County medical examiner's website, which termed her death a homicide.
Anastasia was found in her bedroom in the 800 block of Cullum Court off Precinct Line Road north of Texas 10 in Hurst.
That afternoon, Anastasia's father alerted a neighbor that his daughter was not breathing, and seconds later police received a 911 call.
Winstanley said Sunday that the department is attempting to connect the family with resources to assist them with Anastasia's funeral.
